Common Questions About Our Heat-Treating Services
With a network of proven brands, advanced furnace technologies, and deep metallurgical expertise, we deliver processes you can count on. Below are answers to some of the most common questions we receive from customers across the industries we serve.
We process a wide range of components, from fasteners, pins, and small hardware to complex machined parts, castings, and precision-engineered geometries. Our facilities are equipped to handle both high-volume runs and specialty batches that require customized fixturing or careful process control.
Our team evaluates your material, geometry, specifications, and performance requirements to recommend the most effective process. Whether it’s carburizing, vacuum heat treating, induction hardening, or aluminum processing, we ensure the method matches your metallurgical and mechanical goals.
To deliver the most precise estimate, we typically request material type, part dimensions, volume, drawings or prints, required hardness or mechanical properties, and any applicable specifications (e.g., AMS, ASTM, CQI-9). More detailed information helps us streamline processing and ensure accuracy.
Turnaround varies by service type, part complexity, and production volume, but our production is built for quality and flexibility. With multiple facilities and specialized equipment, we can accommodate fast-track orders and maintain reliable scheduling across a wide range of applications. Typical turn times range from 3 to 7 business days but can vary based on part specification, volume, and backlog. Please reach out to our sales team for more accurate information.
Each brand within Thermal Process Holdings operates under unified quality standards, strict process controls, and comprehensive testing protocols. We perform hardness testing, microstructure evaluation, and verification steps to confirm that every part meets your exact specifications before it leaves our facility.
